Article Abstract
Handgrip strength (HGS), cardiorespiratory fitness (CRF) and body size, shape, and composition are all related to cardiometabolic health and are associated in cross-sectional settings. Their longitudinal relationship is less clear. We used observational data from the Study of Health in Pomerania at baseline (SHIP-TREND-0; 2008-2012) and follow-up (SHIP-TREND-1; 2016-2019) with 1,214 men and 1,293 women. HGS was measured with a hand dynamometer. CRF was assessed using cardiopulmonary exercise testing. Linear regression models were adjusted appropriately. Several sensitivity analyses were performed. From baseline to follow-up (7 years) HGS decreased in men (3.5 kg) and women (0.8 kg). VOpeak lessened in men (36 ml/min) and increased in women (53 ml/min). We only found significant relations in men where a 1 l decline in VOpeak was associated with a 0.87 kg larger decrease in fat free mass and with a 1.15 kg stronger decline in body weight. All other analysis revealed non-significant findings. This longitudinal analysis suggests that age related changes in strength and CRF are not related to body size and shape but only composition (in men). A novelty of our findings are the sex-specific aspects given that strength decreased much stronger in men compared to women.

Osteoporotic hip fractures are a considerable cause of pain and disability particularly among the elderly. Osteoporosis causes loss of bone stability, which in turn leads to an increased risk of fractures especially in metaphyseal bone. Moreover, the body's capacity for healing is diminished, resulting in prolonged recovery times following these fractures.

The Mediterranean Sea is home to a wide variety of fish species that exhibit carnivorous behavior, particularly during the juvenile to pre-adult stages. This study aimed to compare the tongue morphology of four Mediterranean carnivorous fish species: the dusky grouper fish (Epinephelus marginatus), John Dory fish (Zeus faber), squirrelfish (Holocentrus spp.), and red lionfish (Pterois volitans).

This study aimed to evaluate mortality due to female breast cancer attributable to overweight and obesity and to estimate the number of preventable deaths with a reduction in the Body Mass Index in Brazil. An ecological study was carried out with investigation of information on overweight, obesity, sociodemographic characteristics based on a national survey carried out in 2013-14; breast cancer mortality rate in 2019 using the Online Atlas of Mortality and Relative Risk Meta-Analyses. The Potential Impact Fraction analysis was carried out, considering the following counterfactual scenarios related to the reduction in BMI: Scenario A - population contingent of women that make up the prevalence of overweight and obesity now composes the prevalence of eutrophy; Scenario B - population contingent of women that make up the prevalence of overweight starts to make up the prevalence of eutrophy; Scenario C - population contingent of women that make up the prevalence of obesity becomes part of the prevalence of overweight.

The present study aimed to investigate the relationship between screen time and the frequency of consumption of ultra-processed foods (UPF) in overweight pregnant women. This was a cross-sectional study that used baseline data from a randomized clinical trial conducted in the Primary Health Care (PHC) network of a Brazilian municipality between 2018 and 2021. Data from the Food Consumption Markers form were used.

Sodium orthovanadate (vanadate), a potent inhibitor of p53, has been shown in earlier work to alleviate total-body irradiation (TBI)-induced hematopoietic syndrome. However, as p53 plays a crucial role in normal spermatogenesis, its suppression may raise concerns about potential adverse effects on male reproductive function. In this study, we investigated whether vanadate exacerbates impairment of male fertility when administered for hematopoietic protection under TBI conditions.
